This SATA Solid State Disk (SSD) comes in a standard 2.5-inch size and has an SATA interface which means it can be used in most notebook computers and mainstream PCs just like a regular hard drive. Instant access speeds, large capacity, high reliability, low power consumption and anti-shock features, making it clear that this Transcend's SSD is the ideal drop-in replacement for conventional Hard Disk Drives. Built-in wear leveling technology also ensures ultra-long lifespan and data-retention durability for prolonged use. With no moving parts, absolutely no noise is generated from the SSD, and much less power is needed for operation, which means less heat is generated as well.
